X Pull connector ? with the cable and hose
A out of the housing.
X Screw hose A onto flange B of tire
sealant bottle :.
X Insert tire sealant bottle : head
downwards into recess ; of the tire
inflation compressor.
X Remove the cap from valve C on the faulty
tire.
X Screw filler hose D onto valve C.
X Insert connector ? into the socket in the
footwell of the second row of seats
(
Y page 286).
! None of the other sockets or cigarette

Y page 149) in the ignition lock.
X Press on/off switch = on the tire inflation
compressor to
I.
The tire inflation compressor is switched
on. The tire is inflated.
i First, TIREFIT is pumped into the tire. The
pressure can briefly rise to approximately
500 kPa (5 bar/73 psi).
Do not switch off the tire inflation
compressor during this phase.
X Allow the tire inflation compressor to run
for five minutes. The tire should then have
attained a pressure of at least 180 kPa
(1.8 bar/26 psi).
! Do not operate the tire inflation
compressor for longer than eight minutes
at a time without a break. It may otherwise
overheat.
The tire inflation compressor can be
operated again once it has cooled down.
If a pressure of 180 kPa (1.8 bar/26 psi) has
been achieved after five minutes, see
(
Y page 320).
If a pressure of 180 kPa (1.8 bar/26 psi) has
not been achieved after five minutes, see
(
Y page 319).
Tire pressure of at least 180 kPa
(1.8 bar/26 psi) is not reached
If, after five minutes, a pressure of 180 kPa
(1.8 bar/26 psi) has not been achieved:
X Press the on/off switch on the tire inflation
compressor to
0.
The tire inflation compressor is switched
off.
X Unscrew the filler hose from the valve of
the faulty tire.
X Very slowly drive forwards or reverse
approximately 30 ft (10 m).
X Pump up the tire again.
G WARNING
If after five minutes a pressure of 180 kPa
(1.8 bar/26 psi) cannot be achieved, the tire
is too badly damaged to be repaired reliably
using TIREFIT.
In this case TIREFIT cannot seal the tire
properly.
Do not drive any further.
